A welding jig device is used for forming a part by welding a plurality of members together, and includes a jig on one side having a joint face on one side, which is adapted to contact one of faces exposed on the outer surface sides of the plurality of members overlaid one on top of the other, and an opening on one side corresponding to a portion of desired welded portions of a part; and a jig on another side having a joint face on the other side, which is adapted to contact another face of the faces exposed on the outer surface sides of the plurality of members W, and an opening on the other side corresponding to another portion of the desired welded portions of the part and not corresponding to the opening on the one side.

An electronic component includes a housing and a cover. The housing includes a concave portion accommodating therein elements. The cover covers the concave portion. A laser-welded portion including a discontinuous portion is provided along a circumference of the concave portion of the housing and fixes the cover to the housing.

A housing includes a concave portion in which components are to be accommodated. A cover covers the concave portion. A first laser-welded portion is provided along a circumference of the concave portion of the housing and fixes the cover to the housing. The cover includes an opening positioned inside of the first laser-welded portion and corresponding to a part of the circumference of the concave portion of the housing.

An electric motor, in particular for a motor vehicle, having a cylindrical motor housing and having a fastening flange, the motor housing having a housing shell which is open both on a first end side and on the opposite second end sides, the fastening flange being configured with a bearing seat, and the fastening flange being connected to the housing shell on the second end sides.

A metal member includes a first plate, and a second plate abutting against and welded to the first plate in at least one butt portion. In the butt portion, a length from a first end to a second end of a welding boundary line between the first plate and the second plate is longer than a length of a straight line connecting the first end to the second end of the welding boundary line.

A laser welding apparatus (1) includes a laser welding head (5) configured to irradiate a workpiece (10) with laser light, a welding filler feeding mechanism (6) configured to supply a welding material to a position on which laser welding is performed, and a hollow structural moving mechanism (100) configured to move a welding unit (50) including the laser welding head and the welding filler feeding mechanism. The hollow structural moving mechanism has an insertion portion (3a) through which wire materials (41 and 62) of the laser welding head and the welding filler feeding mechanism are inserted.

A laser welding by-product removal device comprises a housing that includes distal and proximate ends separated along a central axis by a peripheral sidewall. A first plenum circumscribes the peripheral sidewall at the proximate housing end and includes a gas inlet and a first plenum base surface that includes a plurality of gas outlet holes. A second plenum circumscribes the peripheral sidewall between the first plenum and the distal housing end, where the second plenum includes a second plenum base surface, radially inner and outer sidewalls that extend axially distal from the second plenum base surface. The second plenum includes a top surface extending between the radially inner and outer sidewalls, and a by-product outlet in the top surface, where at least one of the second plenum base surface and the radially outer sidewall includes a plurality of by-product inlet holes.

The invention pertains to a laser machining system includes first deflection optics, second deflection optics, and a coupling device. The first deflection optics deflect a machining laser beam in two directions in space. The second deflection optics deflect a measuring beam in two directions in space independently of the machining laser beam. The coupling device is arranged in a beam path of the machining laser beam and couples the measuring beam into the beam path of the machining laser beam.
